32 Troubleshooting General failures and consequential solutions are listed in this section. When you encounter these issues, please deal with them in the following corresponding ways. 1. The screen remains dark after power on: (1) Check the power plug is correctly inserted. (2) Check the power switch not faulty. (3) Check the battery is fully charged. (4) Restart the instrument after completing inspections above. 2. After the signal is sampled, there is no corresponding waveform displaying: (1) Check if the probe is correctly connected to the signal connecting cord. (2) Check if the signal connecting cord is correctly connected to the BNC. (3) Check if the probe is correctly connected to the item under test. (4) Check if there is a signal generated from the item under test (you can connect the probe compensation signal to the problematic channel to determine the reason for the problem) (5) Resample the signal. 3. The voltage amplitude measured is higher or lower than the actual value (the error usually occurs in use of the probe): Check if the attenuation coefficient of the current channel matches with the attenuation ratio of the probe. 4. There is waveform displaying but it s not stable: (1) Check the trigger source: check whether the Source in menu of TRIG is the actual operating channel. 32

33 (2) Check the waveform is correct: it is easy to regard the wrong waveform as the real one when a high frequency signal is connected to the instrument. Make sure that the current time base is correct. (3) Check the trigger type: Edge trigger suits the general signal and Video trigger suits to video signal. Only in the correct trigger type can the waveforms stably display. (4) Change the setting of trigger holdoff. 5. No display after pressing Run/Stop : Check whether the trigger Mode is Normal or Single, and if the trigger level exceeds the waveform range. If yes, set the trigger level to the middle or change the trigger Mode to Auto. Note:pressing Auto could automatically replace the above setting. 6. The waveform displays like a ladder: (1) The horizontal time base may be too low, you can increase it to improve the horizontal resolution so as to correct the waveform. (2) The lines between the sample points may also cause ladder-like displaying if the Type in menu of DISPLAY is Vectors. Please turn the Type to Dots to solve the problem. 7. Measured multimeter parameter proves to be inaccurate: (1) Check if the current measurement range is appropriate for the measured value; (2) Check the instrument is in calibration period, and contact RS for new calibration if necessary. Data measured beyond the calibration period are inaccurate. 33
